Hey everyone, this is Justin from Level Up Lunch. In today's episode we will look at how we can sort a collection of objects using java 8 syntax. To get us started, we created an Employee class with a few different attributes such as employee number, first name, last name and hire d...
Java 8 brings all the goodness of lambdas to enable us to program using a declarative style. But is it really free? And should we be concerned about the price we have to pay for the new programming goodies? Here’s an example where we might have to worry. Consider sorting instances of ...
